Physics: Vernier - Capacitors
by Vernier Software & Technology - Data Collection with Probes Lesson


  • Measure an experimental time constant of a resistor-capacitor circuit.
  • Compare the time constant to the value predicted from the component values of the resistance and capacitance.
  • Measure the potential across a capacitor as a function of time as it discharges.
  • Fit an exponential function to the data. One of the fit parameters corresponds to an experimental time constant.
